MANIFOLD BILLING ATTACHMENT FOR TYPEWRITING MACHINES.

.Application led March 24, 1924. lSerial No. 701,270.

Thisl invention relates to a novel and improved manifold'billing attachment for type' writing machines -and consists of the matters hereinafter described and more particularly pointed 4out in the appended claims. Al-

though shown as an attachment. to a marketed typewriting machine,in the present instance the Monarch typewriter, it is to be understood that the invention may be built into l0 or incorporated with typewriting machines as manufactured.

The invention relates more specifically to improvements in an attachment for ty ewriters of the kind shown in Letters-Patent No. 937,374 heretofore issued to me on October 19, 1909, by means of which a multiform billing sheet, together with a carbon aper 0r carbon ribbon is wound upon the p aten of the machine to make manifold copies at one writing. As will appear, the multiform billing sheet may be of the single sheet type` shown in my Patent No. 932,713, August 31,v

1909, or it may be of the folded sheet type shown in my Patent No. 1,017,798, February l5 13. 1912, in which the sheet has all the` forms printed on' one side,v (in the folded sheet type, on the similarly-faced sides of the two sections of the sheet) with the first form, at the top of the sheet, of a height equal to the length of the circumference of the platen and with the downwardly succeeding forms progressively increased in vertical. dimensions, both as to height and as to the spacing between the horizontal lines. of the forms.

35. The carbon paper or ribbon is wound with its copying surface againstthe printed face of the sheet (a carbon face being preferablyv provided on the rear face of the top section in the case of the folded sheet) ,and the orig- 40 inal typewritten matter is produced on the bottom lform of the billing sheet, which will l constitute the outermost winding of the sheet upon-the platen. y

' The object of the invention is to: provide 15 novel and improved features in the attachment by means of which the billing sheet may be automatically fed to and suitably engaged with the platenso that it may be rapidly wound upon the platen with the carbon.

ribbon the required number of revolutions: and thesheet may be automatically ejected a t'ter it has been written upon` without any handling or guiding of the sheet by the operator. lt is of course to be understood that other styles or kinds of work sheets besides those illustrated .and described herein may be vemployed with the present invention.

This and other objects and advantages of the invention will be more easily ointed out and recognized as I proceed with my 00 specification.

Referring now to that embodiment of the invention illustrated in the drawings :10 indicates a typewriter of familiar construction, that is the Monarch typewriter, provided with the'improved manifold billing 105 attachment; and 11 indicates a'table supporting thev same. l12 indicates the main frame of the typewriter; 13, the paper carriage, whiehhas end plates 14, 15; and 16 indicates the platen. The platen has in its surface a longitudinal groove 17 and a removable or hinged rod 18 by means of which the end of the carbon ribbon or reproducing sheet 19 is gripped and connected to the surface of the platen.

20 indicates the tension or springroller upon which the carbon ribbon is normally wound. In the present instance, said tension roller is mounted on the paper carriage 13 vertically above the platen. Said roller constitutes a rewind roller for the 'carbon ribbon after the typewriter has been operated upon the billing sheet and maintains a tension on the carbongsheet'while it is being wound with the billin'g sheet upon the platen, thus insuring a smooth winding about the platen.

Back of the tension roller 20 isa second roller 21.' This is also atension roller and has wound upon it two laterally spaced guide` tapes 22, whichk have their ends attached to the platen 16 by means of the groove and rod 17, 18, as in the case ofl the carbon ribbon 19. The guide tapes 22 are spaced in such manner that 'they will engage the billing sheet near its lateral margins and beyond the space on the sheet to lbe written upon. As shown in Fig. 3, said` tapes are wound uponspools 22a, which are fixed on or integral with the tension roller` 21, thus maintaining the tapes in the desired spaced relation. The tension roller 21 is mounted on the paper carriage 13. The tension roller 21 is hollow and contains a coiled spring 2lx which tends to turn it on the axle 21Y. The tension roller 20 is provided with a similar turning spring (not shown).

The tension roller 20 for the carbon ribbon is preferably provided with laterally spaced itlanges 20,- 2 0:l see Fig. 2) to engage the lateral edges of the carbon ribbon and guide the ribbon laterally in its winding and unwinding movement upon the platen. One of said flanges is removable.

The plane of the carbon ribbon 19 and the plane of the tapes 22, in their paths from their respective tension rollers to the platen, meet in a sharp angle at the surface of the platen and it is into the apex of this angle 'that the end of the billing sheet must be delivered and held to the platen in order that the billing sheet and carbon ribbon may be operatively wound together upon the platen in the required .mannen lt will be convenient here to ydescribe the multiform billing sheet itself. As shown in Fig. 7, it is a single sheet 23, with four forms 24, 25, 26, 27,-24 being the top form. The sheet is upside down in position as it appears when it is fed to the platen and looked at from the rear of the platen. The forms are of vertically increased dimensions and spaced as heretofore so that each form may completely encircle the platen when the sheet is wound around the platen with the carbon ribbon 19 and tapes 22. At the top 2@ of the sheet is provided an extension or short flap 24b which is folded back towards the rear face of the sheet.

A stack 23x of the sheets 23 (see Fig. 1) is supported. in any convenient manner above thetension rolls 20, 21 in position for the vtop sheet of the stack to be fed into the angle between the carbon ribbon 19 and the tapes 22. As shown, a board 28 is supported in a plane inclined from the table 11. Any suitable supports 28a connect the board to the table. The stack of sheets 23X are held on the board by a pin 28", fixed at the top of the board and projecting outwardly therefrom (see Figs. l and 18) to engage in a hole 28y formed at the bottom of the sheet. (See Figs. 7 and 8.) The pin 28? has a knife edge 28d at the top, so that although the pin will act to support the stack of sheets 23", a slight, but positive downward pull will act to withdraw asheet from the stack without` disturbing the rest of the sheets in the stack. 'I/he board preferably has side flanges 28" to engage and guide the edges of the sheets on their way towards the platen.

In front of the board is supported a .reciprocating plunger 29, which is adapted to deliver the sheets in succession from the I stack to the laten. Said plungen comprises a cross hea 30 slidably mounted on vertical guide bars 3 1` 31; and laterally spaced depending fingers 32, 32. The guide bars 81 are attached at their top ends to a yoke 33 which is connected to the flanges 28c of the board 28. Said guide bars carryat their bottom ends a'transverse bar 34. which acts as a stop to limit the downward movement of the cross head 80.

The sheets 23 are arranged in the stack with their flaps or engaging devices 24h towards the front and in a position somewhat below the topmostposition ofthe bot tom ends of the fingers 32, and in the path to be followed by said fingers. As. the fingers descend. their ends engage in the angle between the tlap 24h and the body of the top sheet 23 of the stack, and carry said sheet downward towards the platen and into the angle btween the carbon ribbon 19 and the tapes 22.

While the lingers 82, 82 deliver the top end of the sheet 23 into the angular space. between the carbon ribbon and the tapes as stated` it is generally essential in order that the said sheet end will be gripped between the tapes and carbon ribbon and wound properly wit-l1 them about the platen. for an additional mechanism to be employed. This is a -devce to` as it were. kick in said sheet end substantially at the instant that the platen begins its rotary winding more ment. In the embodiment of the invention 'bearing in the table 11) illustrated herein, this device consists of a sleeve 35 (see Figs.- 3, 5 and 6) iixed on the tension roller 21Y (which carries theta-pes 22) midway between the spools 22a on which said tapes are wound. Said sleeve is preferably made of yieldingmaterial, as' for ex ample, rubber, and is Aelliptical in cross-section. It is fixed on-the roller with the periphery of the shorter axis n'ext the path to be followed by a billing sheet on its Way to the platen, as shown in full lines in Fig,

19 and will thus be wound with the carbon ribbon-and tapes upon'the platen. e

Any suitable mechanism, hand operated or -power driven, may be used to rotate the platen the required number of turns and to reciprocate the fingers 32 in suitable timed relation. As shown, the mechanism is operated by a treadle y36 (see Figvl) pivoted at 37 to the fioor'below the typewriter and having pivotally connected to it at a point remote from the pivotal point ,37 ,a vertical link 38. Said link extends up through the table 11 and is above the table operatively connected to a bell crank lever 39 pivoted at 40 to a standard 41 mounted on the table. One arm 39` of the lever 39 (-to which the link 38 is connected) carries a one-way pawl 42 adapted to engage a pin 43a on a verti cally movable rod 43. (with a suitable guide which is con nected to a lever 44 fulcrumed at 44a to a laterally extending bracket arm 44b fixed to the' yoke The other end of the lever 44 is pivotally connected to a short link 45 which is in turn pivotally connected to the cross head 30.V A Acoiled tension spring 44c normally holds the lever 44 in position so that the cross head 30 and the fingers 32 carried thereby are in their uppermost position.

The platen is driven by speed increasing gearing comprising a large gear 46 mounted on the end plate 14 of the paper carriage (see Fig. 4), an intermediate idle .gear 47 and a pinion 48 on the proximate end of the platen shaft. 46*a which is connected by a universal Iioint 46" to a horizontal telescopic shaft 49 which extends over towards the standard 4l. 50 indicates a small bevel pinion on the end of said shaft which is engaged by a larger bevel pinion 51 located in a plane at right angles to the plane of the pinion 5() and connected bysuitable clutch. or ratchet mechanism 52 The. large gear 46 has a stud- (see Fig. 14) to a spur gear 53 located in a parallel plane adjacent to and on the same axis as the bevel gear 51. The arm 39" ofthe bell crank lever 39 carries a segmental spur gear 54 which is adapted to engage the spur gear 53, The tread'le 36 is normally retained 1n its upper positionv by means of a coiled tension spring 55 connecting it vwith the table 1l The operation of this mechanism is as follows: VWhen the treadle 36 is depressed, it swings the bell crank lever 39 upon its axis 40 in the direction of the arrow. .In

the first part of the movement of the bell` crank lever 39, the one-way pawl 42 carried by the arm 39a acts through :the pin 43a to-v pull down the rod 43 and swing the lever 44 (against the action of the spring 44) to depress the crosshead 30 with its fingers 32, which feed one of the sheets 23 to the platen 16'y as heretofore described. The parts are sodesigned that when' the fingers 32 have delivered a sheetto the platen, the one-way pawl 42 slips by the pin 43a on the rod 43 and releases said'hrod, thus permitting the lever 44 to return to its normal position and restore the fingers 32 to their `uppermost position. J ust about the time the pin 43a is thus disengaged, the segmental gear 4I54 engages the spurgear 53, and in thel second part of the movement lof the ybell crank lever 39, the spur gear 53 and the bevel gear 51lare rotated t in the direction of the arrow.) thereby rapidly rotating the platen 16 through the described gear trains. The` downward` movementI of the treadle 36 is arrested when the platen has been rotated a predetermined number of times-such. arresting means as shown, consisting of a pin 56 on the standard 41 'to be engaged by the arm 39a of the bell crank 39. Upon release of the treadle the bell crank lever is returned to its normal position,-the gmental gear 54 yin its return movement in engagement with the spur gear 53, being ir operative to rotate the bevel pinion 51 in the reverse direction due to the clutch 52.

At the left hand end of the platen 16 is provided a stud shaft 63 and knurled knob 64 for rotating the platen for line spacing and the like. The usual line space mechanism (not shown) xfor turning the platen step-bystep is provided. A pawl and ratchet 65, 66 are provided adjacent this knob between the frame and the end of the platen to hold the platen againstthe spring tension exerted by the carbon ribbon 19 and the tapes 22, 22. Thus` after the outer bill forln has been written upon. the release of the platen by. the disengagement of the pawl 65 from the ratchet 66. permtts the tension of the carbon ribbon 19 and the tapes 22 to operatevto unwind thecarbon ribbon, tapes and the billing sheet from the platen. This is brought about very rapidly with the result that the sheetl is ejected. A release arm 67 of an'y familiar construction is provided adjacent the pawl and ratchet 65, 66 for disengaging the platen as described.

As will be manifest, it will be necessary for the operator to have the release arm 67 in position such that the last named pawlV into writing position, the release arm 67 will be let go and the feet may then be lifted from the treadle 36, after which the typewriting operation may be proceeded with in the normal manner. As -will be understood, the number of revolutions will depend upon the number. of forms on a billing sheet, which in the present case is shown to be four. Where a smaller or greater number of forms are used on a billing sheet', the location of the arresting pin 56 on the standard 41 and the arcuate length of the seg mental gear 54 will be modified accordingly. .I

In Fig. 8 I have shown a folding form of billing sheet 70. In this case each section 7 1, 72 of the billing sheet is provided with a set of forms, four in number, as in the ease of the single sheet shown in Fig. l7, and each section is also provided' at its top end with a iiap 73, 74 respectively. The one section 71 is also provided with a carbon face 75 on the side reverse to that on which the forms are printed, so that what is written on a form on one section will be reproduced on the similarly7 placed form on the other section. Thus, manifestly eight forms may be written at one operation in the case of such a billing sheet as compared to four in the case of the one shown in Fig. 7. In arranging the sheets for delivery to the platen they are stacked and operated upon ir the same way as in the case of the single s eet.

In order that the sheet may be guided in its ejection from the platen upon the actuation of the release arm 67, I preferably provide a guide or throw-off plate 7.7 (see Fig. 1). Said guide plate is attached to the stop 34 at the bottom ends of the guide members 531 for the crosshead carrying the fingers 32 and is located, as indicated in Fig. 6, so that it will project into the path of the sheet on its way to the platen. This guide plate is This,

movement of the sheet it will be pushed aside and will not interfere with the delivery of the sheet to the platen. AUpon the ejection of the sheet, however, the guide plate 'will strike the upwardly moving end of the sheet and guide the sheet, towards the front or towards the back of the -machine, depending upon which way it isl adjusted (towards the front as shown in Fig. 6) and thus insure the discharge of the sheet towards the point desired.

As will be understood, t-he specic form of billing sheet with the folded flap at its top end is merely one example of a billing sheet provided with means adapted to coa't with the specific form of deliveryiinger illustrated and described herein as one eX- empliiication of such finger. No claim herein is made to the form of billing sheet illus trated, which 'is claimed specifically in another application relati-ng thereto- In Figs. 10, 11 and 12 I have shown a modified form of feeding and delivering means for the sheets.- Instead of the fingers 32 and the kick-in device 35. I provide a thin plate which is attached to the tapes 22X and eX- tends transversely between them. The tension roller 21X for the tapes in this case is placed somewhat farther away from the platen andthe sheet support 28x is placed so that the top ends of the sheets provided with the flaps 24J extend down below the tension rol1er'21. I'n addition, the sheets are so formed in this case that the flaps are turned towards the rear insteadof towards the front as in the other case,-that is to say, the flaps are turned towards the printed 'rov face of the sheet, instead of towards the'unprinted face as vin thetirst case.

` When the tapes are fully wound upon the' tension roller, the plate or blade 80 is located in a position somewhat above the ends yot' the billing sheets. When the platen 16x is rotated to wind the carbon ribbon and tapes thereon, the blade 80 carried by the tapes, on the way towards the platen engages the flap 24h of the lowermost sheet in the stack and carries the sheet towards the platen where it is interwound between the tapes and .the carbon ribbon, as shown in Fig. 11. The plate 8O is transversely curved to conform to the curvature of the laten so that when it engages the platen it will not make a bump or projection on said platen.

As will be manifestI from a consideration of Figs. 10 and 11, it is necessary in designing the platen winding mechamsm, to provide that the platen be wound, in addition to the number of times required for the frms on the billing sheet, through an additional are equal to the distance of the end of the billing sheet from the platen when the sheet is held on its support prior to the feeding and delivering of the sheet to the platen.

made flexible, so that in the downward It will also be manifest that the mechanism fingers, it is preferred forms on a billing -way tothe platen. ,sheets-Tis supported as required for operating the crosshead 30 and fingers 32, namely, the rod 43 and the lever 44, will be omittedwhen this type of sheet feeding and delivering means is used.

In order to accommodate the support for the sheets to sheets with different-numbers of forms thereon, it is preferableto provide a luiality of holes or openings 28Z (see Fig. 105) in the board 28X to receive the sheet supporting pin 28". The distancebetween these will be equal to the distance between the sheet so that the ends of the sheet next to the end of the platen will always be in a predetermined position with reference to the feeding and delivering mechanism.

When a delivery device such as that shown in Figs. 1`0 to 12 inclusive, is used, the weight'of the sheets in the stack above the bottom sheet will provide pressure against which the delivery device 80 may operate when gripping a bill and carrying it on its Where the stack of in the case of the delivery device'shown in Figs. 1 to 9 inclusive, and the top sheet is engaged by the delivery to provide a pressure to act upon the bottom ofthe stack so as to always hold the top sheet in the path of the delivery finger. This pressure is lconv veniently provided asshown in Fig. 1 by larms 93a means of a block or follower 90 supported in suitable guideways for movement at right angles to the stack of sheets through a hole 91vin the board 28 near the bottom end of said board, and yieldingly held against the bottom ofthe stack by means of a coil sprin' 92 engaged against tl` e back of the follower or block 90.v Theyielding pressure for the blockis provided by means of a coil spring engaged against its back and secured at its ends to short bell crank levers 93, attached The arms 93a to are in the path of laterally extending rods 94 carried by the cross head 30. Thus,l when the plunger carrying the fingers has passed to its lower-most position, the cross head 30 in bringing the lingers to this position has caused the rods 94 to strike the of the bell crank levers 93 and release the tension of the spring', as they do so swinging the other arms 93 of the bell crank levers into the path of the .pins 94 on the cross head. Thus, when the cross head returns to its uppermost position the second pair of arms 93b are struck and the spring is made to again engage the back of the block and hold it to push the stack of sheets upwardly towards the path of the fingers.
